Which of the following solutions has the highest pH? Can you also explain how to determine if a solution has the highest pH?

a) 1.00 mol/L HNO3 (aq)
b) 1.00 mol/L KOH (aq)
c) 1.00 mol/L NaCl (aq)
d) 1.00 mol/L CaCl2 (aq)

At equal concentrations, which of the following solutions is the most conductive?

a) C6H12O6 (aq)
b) CH3COOH (aq)
c) HClO4 (aq)
d) CH3OH (aq)

Answer (3)

The solution with the highest pH is KOH, because it's a strong base. The most conductive solution would be HClO4, because it's a strong acid and dissociates into ions which are responsible for conducting electricity. ;

A 1.00 M solution of KOH (aq) would have the highest pH because it is a strong base. A 1.00 M solution of HClO4 (aq) would be the most conductive as it is a strong, fully ionizing acid that produces a high number of ions. ;

The solution with the highest pH is KOH due to its strong basic nature, while the most conductive solution is HClO4 because it dissociates completely into ions. Neutral salts like NaCl and CaCl2 do not significantly affect pH. In contrast, weak acids or non-electrolytes like glucose and methanol conduct electricity poorly.
